A timeout while waiting for a device' signature has shown that our
error path wasn't correct. The shutdown of the ports command engine
always timed out. Fix that by waiting for FR (FIS Receive Running)
to be cleared independently from CR (Command List Running) and after
clearing FRE (FIS Receive Enable).

Add the Mobile Panther Point (PPT) AHCI controller (DEVID 0x1e03) to
the list of tested controllers. Also comment the only other listed
controller (Mobile ICH9).
The PPT AHCI controller was tested with a QM77 chipset on a Kontron
KTQM77 board.

This adds a new interface for storage devices. A driver for ATA and
ATAPI drives on AHCI host controllers comes along.
The interface is very simple and was designed to match FILO's needs.
It consists of three functions:
void storage_initialize(void);
Initializes controllers. Should be called once at startup.
storage_poll_t storage_probe(size_t dev_num);
with typedef enum {
POLL_NO_DEVICE = -2,
POLL_ERROR = -1,
POLL_NO_MEDIUM = 0,
POLL_MEDIUM_PRESENT = 1,
} storage_poll_t;
Looks for a drive with number dev_num (drives are counted from
zero) and polls for a medium in the drive if appropriate.
int storage_read_blocks512(size_t dev_num,
u64 start, size_t count,
unsigned char *buf);
Reads count blocks of 512 bytes from block start of drive dev_num
into buf.
